Patented Juno 0, 1M y To all whom it my concern:I

Be it known that'I, HERMANN SCHRDER, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Phonograph-Horns, of which the following is a specification.

This invention contemplates certain new and useful improvements in phonographs and relates particularly to an improved construction of phon which'will result 1n re i'oducin va mellow sound without any of t at lmeta lic characteristic or tone uality which is such an obectionable incidle ic horn.l

With this and other objects in view as ear as the description p'roceeds, the invention consists in certain constructions, arrangements and combinations ally describe and then oint out the novel features in the appended) claim. A r

In" the accompanying drawings, I have illustrated my improved construction of phonograph horn as embodied in that type ofphonographs where the sound amplifying means is mounted in a stationary manner within a casing or cabinet, 'upon which the disk or cylinder record is mounted.

In the drawings: re 1' isa pers ective view cfa phonograp rovements of my invention. Fig. 2 is a on itudinal sectional view. (Jgorresponding and like parts are referred to in the followin description and indicated in all the views o the drawings by the same reference characters.

This ap lication discloses an invention whichhas ee'i divided out of a rior application for Letters Patent of t e United States,#360,178, filed March 2, 1907, vand the present invention relates solely to the construction ofvsound amplifying means or horns.

In the accompanying drawing I have shown for the purpose of illustration only,

` a cabinet o r case 1 upon which a disk record 2 is mounted, 3'designating the taper arm ograph horn or megaphone nt 'of the ordinary metal-v thatjn. practical o carrying the sound' box or da hragm and its stylus, and 4 designating he connection between the plilfying. means mounted within the case.

. Y ably com osed of wood one end o the case with'the extension or consuitable manner, the said extendi ta ered and being elliptical in horn preferabl the case 1 an wards its rear en cross section. l L preferably also wood,'extend across the om 5'at the front and rear ends thereof, the ends of'said cross bars being secured-to the body of the horn in any desired manner, and a set of tuni pegs 7 is mounted in each of said bars 6. trin 8 extend longitudinal of the body of the lori'i and have their en secured in the well known way to the tuning pegs 7, said strings being the ordinary violin s trings or strings of an other similar instru: ment. 'It is obvious t at' the strings 8 may beheld at any desired degree of tension, and

as the sound issues rom the horn and produce a tone qualit which will be mellow and without the o "ectionable metallic features so common wit the ordinary phonograph horns. A

Having thus described the invention, what is glaimed as nlglis: d ound am an mo ifying' for phono ralpdhs, enngibodyi'ng a tapered body ortion 'el 'ptlcal 'in cross section, ower front and rear cross bars secured at their ends only within the said body ortion and otherwise spaced from the walls reof tuning pegs mounted in said cross bars' and strings secured to and stretched between the said pegs and extending longitudinally o f the body portion. In testimony whereof'I affix in presence of two witnesses.

HERMANN SCHRDER.
